I would have to say that something is wrong with your throttle position sensor, throttle relay, or your throttle is dirty and sticking. I would check the sensors and the relay with a volt meter first. You can take off the air intake hose and see if your throttle is dirty. If it is just get some carb cleaner and spray in it. That should take care of the problem.



CORRECTION: YOU HAVE A STICKY THROTTLE CABLE. GO TO A MOTORCYCLE DEALER PARTS DEPARTMENT AND ASK TO PURCHASE A CABLE LIBRICATION TOOL.
OPEN THE HOOD, ON THE FLOORBOARD INSIDE THE CAR, PLACE LOTS OF NEWSPAPERSAROUND THE THROTTLE PEDAL (ITS GONNA GET MESSY), LOCATE THE THROTTLE CABLE (TOP CENTER OF MOTOR OFF TO THE PASSENGER SIDE UNDER A 5X5 IN BLACK PLASTIC COVER) AND CLAMP THE NEWLY PURCHASED TOOL, AND WHILE YOU ARE ARMED WITH WD40 OR LIQUID WRENCH (EITHER IS GOOD AND MUST HAVE A PLASTIC STRAW WITH IT, PLUG THE STRAW INTO THE HOLE ON THE NEW TOOL AND SPRAY FOR 2 MINUTES...

NO MORE STICKY CABLE, FLOOR AT WILL....

Sure, turn it sideways and push it in the back hatch

Autozone.com has vehicle repair guides. You should check it out and know what size your engine is.

The transfer case will not bolt to a 2wd transmission.

It is the tiny valve that lets air in to your tire but not out (unless you push it in with a nail or similar "pointy" thing)

User Avatar

First check the fluids. Then if that isn't the issue, check the thermostat. I ran my car hot, and fixed it yesterday.

drain coolant then remove thermostat housing remove thermostat replace with new one spring to block

Something can be taxing the work of the alternator, or the alternator can be weak and needs replaced.

It will bolt right in but, the "Y" pipe on the exhaust system from the 305 will not fit on to the 350.

Yes, I do, but in order for you to obtain one you will need to go to an auto parts store. Haynes makes a manual specific to your car.

If you looking behind or on the side of the power steering pump, you'll see a bolt. When you loosen the bolt, the pump will slide down and loosen the belt.

The 7.3 liter powerstroke diesel has a 15qt oil capacity. When doing an oil change I would recommend putting in 14qt. first, recheck and top off/add as needed, so not to over fill.

A possibility is the floater, just like the one in your toilet, has come disconnected somehow. The same thing is occurring in my suburban because it was not put back together properly after the gas tank was taken down for repair work.
